  • ALD is a disease caused when peroxisomes lack
    a membrane protein needed to import a specific enzyme and/or long-chain fatty acids from the cytoplasm.
  • peroxisomes are spherical organelles made up of
    a phospholipid bilayer and a crystalloid core
  • in leaves peroxisomes can carry out a reaction that
    uses oxygen and releases carbon dioxide
  • the enzymes in peroxisomes are synthesized by
    free ribosomes
  • Which of the following activities are characteristics of peroxisomes? I. Catalase activity II. Possess a glyoxylate cycle III. Degradation of very long-chain fatty acids IV. Produce dihydrogen
    I AND III
